Tsunami alert as Chile hit by powerful earthquake

I live on a 11th floor apartment in Sao Paulo, Brazil (near Av. Paulista), and I felt this quake very slightly! It was very subtle and I thought first that I was just feeling dizzy or something. Then I searched for "terremoto" (earthquake in spanish) on Twitter and then I found a bunch of posts. Isn't it crazy that I could feel this from over here?

According to Google Maps, I'm approx 2500 kilometers (1600 miles) from the epicenter.

Earthquakes, and the twitter responses to them, have been the focus of some pretty interesting academic studies that I've read (2011 Christchurch, NZ was what I studied). If I still had access to the academic journals, I'd pull up some articles. They present fantastic case studies of how using twitter user lat/longs, time logs, and nlp can be very useful.

When I lived in California I would often do a twitter search after feeling a small earthquake. If there weren't any results, I would usually assume it was a truck passing by or something like that.

Very often there would be tweets about the earthquake several minutes before the official USGS page for the earthquake was created.
